“I have to make an apology,” read the caption Rousey posted with the side-by-side photos hours later. “I was sent a picture to share on social for Fallon that was altered without me knowing to make my arms look smaller.”

"Just because my body was developed for a purpose other than f—ing millionaires doesn't mean it's masculine," Rousey said last summer in a video promoting her UFC fight with Bethe Correia. "I think it's femininely badass as f— because there's not a single muscle on my body that isn't for a purpose."
